When problems show up
Most problems on this year showed up between 750 and 20,000 miles (1,200–32,000 km) (the middle half of the 21 complaints, of all 23 filed so far, that listed a mileage).
- At 60K, 100K and 150K miles (97K, 161K and 241K km) Past the range where most problems showed up: it has likely had them or dodged them, so repair records matter most.
This is when owners who had a problem reported it, not the odds that one car will have it.
Questions to ask the seller
- Were recall 11V538000 (visibility) done? Ask for the dealer printout, or check the VIN.
- Does it accelerate and hold speed smoothly, with no surging or stalling?
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Infiniti sent dealers 138 repair notes for this car. Was this one done: “Transmission shift issues and/or a/t dtc stored”?

How serious. Out of all 23 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

In owners' words
My Infiniti G37 yr 2011 had an experience with unintended acceleration in the parking lot, when I was driving about 5 mph and about to stop my car.

It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
